Use google, you'll find enough proof to see that our world is slowly shifting and that it had a greater shift or two already (although not a 180° one ). And do check up at what speeds this is happening, none of this can cause "2012".

i think a stars life cycle is show in colors blue is the last which means is the hottest and then it will die out and implode its self creating a black hole killing all of us saw this on the history channel o.O

I'm not sure, but I think that our Sun is too small to end up going nova and creating a black hole. But even if it doesn't, once it starts changing we're fucked anyways. But (again but) this isn't gonna happen till 2012.
